FPGA Implementation of the RC4 Stream Cipher using Artix-7
Abstract: The RC4 (for Rivest Cipher 4) encryption algorithm appeared in 1987. Its designer is none other than Ronald Rivest, one of the three inventors of the RSA algorithm. This algorithm is distinguished by its great simplicity and speed of encryption. The details of the algorithm were kept secret until a description, probably obtained by reverse engineering, was posted on the Cipherpunks mailing list in 1994. Speed and flexibility of RC4 …

METALLURGY OF INVESTMENT CASTING TECHNOLOGY
Abstract: Investment casting is the most widely used process for several centuries, known as ‘lost wax casting’ or ‘precision casting’. This process is known to produce complex castings with good surface finish and dimensional accuracy. Poor quality of castings is always marked by inadequate surface finish, hardness and excessive shrinkage of the wax pattern. This review paper discusses on the history of investment casting technology, its processing techniques and parameters, casting …

A Mini Review on Applications and Uses of Alloys
Abstract: Alloys are mixed of metal with other metal or non-metal in the same group that are prepared by mixing of the metals in their molten state through physical processes. An alloy is a mixture of two elements, one of which is a metal. Alloys often have properties that are different to the metals they contain. This makes them more useful than the pure metals alone. For example, alloys are often …

Nanocrystalline Silicon Carbide for Implants
Abstract: Nanocrystalline silicon carbide (SiC) is a wannabe material for artificial heart valves fundamentally because of its low weight, high quality, intense hardness, wear resistance, latency (SiC does not respond with organic liquids), and disintegration resistance. Oxide clay materials, for example, alumina (Al2O3) and zirconia (ZrO2) are regularly utilized for restorative applications like inserts and prostheses due to their breathtaking biocompatibility and high wear resistance. Sadly, oxide earthenware production can't be …
